Australian Broadcasting Corporation radio host Richard Glover was on Monday taking a well-earned break after completing a world record breaking 24-hour interview, the network said.
Glover sat down with Australian author Peter FitzSimons intent on smashing the previous Guinness World Record of 12 hours and 30 seconds held by Spain's Pedro Ruiz, set in Madrid in 2009.
In the end they doubled it with observers from Guinness World Records on hand to supervise and ensure they abided by strict rules, including that no questions be repeated, and that no other people be interviewed.
The chat at the ABC's Sydney headquarters ended Monday morning and both men said they were exhausted.
"I felt like throwing up at 8:00am. I feel OK now," Glover said with more than 90 minutes on air still ahead of him, ABC reported.
FitzSimons said: "I did it tough between 4:00 am and 5:00 am."
Sascha Rundle, content director with the ABC radio station where Glover works, said it went beyond what either man expected.
"It was quite funny though because two men, being blokes, they decided of course that it wasn't enough to simply beat the 12-hour record by, say, 10 minutes or 30 minutes," she said.
"No, they had to double, they really did have to smash the record."
